To all whom it may concern; Be it known that Buxmr'mno H. Howann andEnnns'r J. United States,- residing, respectively, at Washington,.District of Columbia, Pittsburgh, in the county of Alleghen and State-of Pennsylvania, have invented certain new and useful Improvements inFeeders for Ingot Molds, of which the following 1 is a specification.

ur invention relates to improvements in top feeders for ingot molds. Theobject of our invention is to provide a feeder for ingot molds adaptedto be readinserted and held on the upper, end of the mold and at thesame time provide a feeder which will prevent the formation of what isknown as piping and at the same time reduce segregation. Another objectof our invention is to provide a hot top feeder for ingot molds havingmeans whereby it is tightly held in the 1 upper end of the mold and-atthe same time providing means to allow for any slight variation in therelative size of the bore of the mold and the exterior diameter of thefeeder. A further object of our invention is to provide a simple, cheapand effective feeder aving certain details of structure and combinationof parts hereinafter more fully set forth- In the accompanying drawingsFigure 1 is a perspective view of a mold showing our improved feederapplied Figure 2 is avertical transverse sectional view of Figure 1. a

TURNER, citizens of the and riphery of which is of a diameter a hasaFigure 11 is a vertical sectional View of-a stilt further modified formof feeder. Figures 12 and 13 are vertical sectional views of modifiedforms of feeders show means for supporting the distributor plate 69therein. v a, Referring now to the drawings, 1 represents the ingot moldand 2 the feeder. As shown, the feeder is of a shape to correspend withthe bore 3 of the ingot mold and a;

while we have shown this feeder of a square form, it is understood thatthe invention can be applied to a feeder of any desired contour. The,feeder 2 as shown in Figures 1 and m 2 of the drawings is of arectangular form having a passage 4-. therethrough which is of adiameter slightly less than the bore of the cylinder. The lower end ofthe feeder 2 has its outer wall cut away as indicated at 75. 5 forming areduced portion 6,the outer peproximately that of the bore of the cyliner and. is adapted to enter the same as clearly shown in Figure 2 of thedrawings. The cut awe portion 5 has its upper end beveled as indicatedat 7 which forms a su porting surface for holding the feeder in tiieupper end of the mold.

From the description shown and described 5 in Figures 1 and 2 of thedrawings itwill be seen that the beveled surface 7 of'the out awayportion of the feeder forms a support for the feeder and also providesmeans whereby the feeder is tightly wedged in the an bore of the mold.This beveled surface 7 particular advantage when there is a slightvariation in the exterior diameter of the reduced portion of the feederand the interior diameter of the mold. This allows the feeder to enterthe mold,until the beveled surface 7 tightly wedges the feeder in theupper end of the mold.

In the modification shown in-Figure 3 the mold is similar to that shownin Fi ures 1 and 2 and. the feeder 8 has the re need portion 9 of agreater length and the tapered wall 10 is also of a greater lengthwhereby under certain conditions the feeder would more firmly wedgeitself in the upper ma end of the mold. 5

In the modification shown in Fi res 4 and 5 we have shown a round modand feeder, the tapered wall 11 starting at its vertical wall 13 whichenters the bore of the mold. -,This form will perform all of thefunctions shown and described in respect to Figures 1, 2 and 3 and willalso allow the feeder to be used in molds, the bores of which show aconsiderable difference in diameters.

In the modification shown in Figures 6 and 7 we have shown ,arectangular mold and feeder 14 having-the Lbore 15 therethrough and theouter wall 16 tapering from the upper end 17 to the lower end 18 wherebythe feeder is capable of being used on molds, the bores of which vary toa greater extent than that described in respect to Figures 4.- and 5.

In the modification shown in Figure 8 the feeder 19 has a central bore20 and its,

lower end 21 reduced and terminating in the curved wall 22 which wouldalso wedge the feeder in the upper end of the mold.

In the modification shown in Figure 9 the feeder'23 is constructedexactly like similar to Figure 5 except that it shows the inner wall ofthe feeder 26 extending in wardly as indicated at 27.

In Figure 12 the feeder is constructed exactly like that shown in Figure5 except that the bore is drawn inwardly as indicated at 28 and adistributor plate 29 having openings 30 therein rests on and issupported by the tapered wall 31.

In Figure 13 he feeder 32 is constructed somewhat similar to Figure 10except that the inner wall 33 tapers from its upper to its lower end asindicated at 34 and is adapted to support the distributor plate 35having openings 36.

Having thus fully described our invention what we-claim is 1. A feederfor ingot molds comprising a'body portion having its outer peripheryreduced towards its lower end. i

2. A feeder for ingot molds comprising a body portion having its outerperiphery reduced adjacent its lower end and having a beveled wall.

. 3. A feeder for ingot molds comprising a body portion having its outerperiphery tapered towards its lower end.

4. A feeder for ingot molds comprising a body portion having a taperedwall below its upper end.

5; A feeder for ingot molds comprising a body portion having its outerperiphery tapered below its upper end.

6. A feederfor ingot molds comprising a bod portion having a portion ofits outer perip ery tapered towards its lower end and terminating inavertical wall.

7'. A feedenfor ingot molds comprising a body portion the upper portionof which is of a greater thickness than the lower portion and the twoportions being connected b a beveled section.

8. A eeder for ingot molds comprising a body portion, the upper portionof which is of a greater thickness than the lower portion and the twoportions connected by a curved section. i

9. A feeder for ingot molds comprising a body portion having a wedgedsupporting outer wall.

10. A feeder for ingotmolds comprising a body portion having its outerperiphery tapered towards its lower end and having a tapered borethcrethrough and a pouring plate placed in the lower end thereof.

In testimony whereof we aflix our signatures.
